iaiaoia Application rum M rch 25,

To al who)?" "'1' Ht/1,5 or: new it 5 Be it known that l, l(l1l'll-2"l:). lllio'ivmi, oitizenjoil? the United Stair residing; at Springfield, in the eoni'ity of .Ilam iden and State of hlassaohiisetts, have invented new and useful Imj n'ovements in liland"Joining a SpQClih cation. i

This invention relates to apparatus for use injoinin imp ro re n1 ents in 'iii'ilifii and per- 1 m together the ends oi a belt, While in place on one or more rol]s,,to permit eonvenieijilv joining of the ends into an endless belt.

iVhile the invention may be used inerally in connection with the joining oi': belts oi various materials, it finds one :1 d vantanteous use in connection with the joining oi" al ow drinimr wire. l n joini'ogr the ends of a. Fourdrinior wire, eonsirierahlo euro liHlSi? he error eised to insure that the wire lies evenly against the roll or rolhg, h tero joii'iingr and that it be i'iniihiirn'iiv lensioned throng root its Witlil'l without unduly stir-itching; the Wire.

This ini' 'entiion has for an ohjeot the pro vision oi an apparatus in! drawing together on endless-i hand while in plane over one. or more rolls, ohariiiztorizeii by means lor partially onooinpa or the hand and pressing; it evenly about its roll or rolls together.

The invention in an embodiment at present preferred is sl'ioivn for illustrative pur poses in the aoooi'i'ipanying drawings, in which.-

or pull taut. the apron 2, Whereliy the wire cloth beneath it is pressed firmly and evenly against the roll or rolls 1. i

i The bars 8 maybe moved toward one an other by the following mechanism, which comprises a pair of jaok mechanisms. Each of the latter includes relatively movable head members l and 6 mounted on a shank 5, one, as l, being; fixed and the other, as 6, liming slidable thereon. semicircular oesses or seats 7 are provided in the adj aoent sides of the members a and 6, and are adapted to'reoeive therein the ends of the bars 3.

A, block 8 i fixed to one end of each shank 5 and carries in threaded engagement therewith a bolt 9 which is so d'sposed that its end will abut the member 6 and move it along the shank l i i A. magnifying glass y is 'irovided and is i in varions positions over the adjacent edges of the Wire cloth; being joined. :inounted upon the shanks 5, are provided With set-screws 12 by means of which the brackets 11 may be adjustably positioned on the shanks 5. A shaft 13 disposed transversely to the shanks. ii loosely in suitable hearings in the brackets U, and set-screws 14., in. threaded engz'igement with the brackets, are 'irovided to clamp the rod 13 in vi rious adjusted positions. A bifur rated arm 15 is slidably mounted upon the shaft 13 and is provided with a set-screw 1.6 for clamping, the said arm. in various positions along" the shaft. The magnifying glass 9 is provided. with a lug; 18 that is adapted to :interfit the slot in the bifurcated end of the arm 15 and is adjustably and pivotally connected thereto by means oi a Clamping screw 19.

In operation, to faoilitate the joining of the ends of a fabric such as a Fourdrinier W e, the material, or 'WlI'B oloth w, is laid around the roll or rolls 1 in the usual manner, and the apron is wrapped over and around the wire in such a manner as to partially encompass it. The ends of the rods 3 are engaged in the recesses 7 of the head 4 and the slidable member 6, and, by means ofthe threaded bolts 8, the members 9 are moved along;- their respective shanks and carry the rods 3 toward one another, As the rods are moved toward one another, the apron 2 is pulled taut and presses the Wire cloth evenly and firmly against the roll or rolls and as the wire cloth is thus pressed firmly against the drum, the edges to be Braelrets li, slid-ably upon the wire cloth joined are moved toward one another for the joining operation. The magnifying glass 9 may be moved to a position over and along the edges of the wire cloth and secured in any desired location, by means of which the weft and Warp members of the wire cloth, as well as their relative location, are greatly enlarged, whereby the stitching and joining of the edges is easily accomplished.

A modified form of theinvention is shown in Fig. 5 and is particularly applicable when it is desired to encompass less of the wire cloth than by the form shown in Figs. 1, 2, 3,and4. v

Blocks 21 are provided and have in threadedv en agement therewith tightening screws 22. tandards 28, preferably of pipe or the like, are fixed to the blocks 21, and

are connected by suitable fittings to the cross-support 25. These standards 23, by being connected to the cross-support, serve to hold the saidolocks in a fixed relation. Members 26, having suitable recesses 27 for supporting the ends of the rods 3, are adapted to rest upon the-roll l and be moved toward one another by action of the screws 22.

In the use of. the apparatus shown. in Fig. 5, the wire cloth is as usual placed around the roll 1 andthe apron'2 is as before laid to partially encompass it. The rods 3 ol the apron are SIIPI'VHlOtl in the recesses of the blocks co and the screws turned to more the blocks 26 toward one another. The apron 2 is pulled taut by the forward movement oi the blocks as and presses that portion of the 't'ahric cucompassed by it evenly and firmly against the drum and allows the tree ends of the wire cloth to be joined. in the usual manner.

hat I claim .is

Apparatus for facilitating the joiniu; ol: the ends of Fourdrinier wire comprising. an apron to partially ein-oinpass the wire when mounted on its roll, rods fixed to each end of the apron, mechanism located at each side of the apron for moving the rods toward one another for tightening the apron each of which comprises, a shank having a head fixed to one end thereof that is provided with a recess for receiving an end of one of said apron rods, a block fixed to the opposite end of said shank, a member slidablc upon the said shank between the said head and block for supporting one end of the other of said apron rods and a screw threaded in the block and adapted to abut the slidable member for the tightening operation.

In testimony whereot l have allixed my signature.
